May warrant neutron-free techniques or enhanced monitoring in CIED patients; leaves open prospective trials for risk mitigation.
Sławomir Blamek (2017) conducted a review in Cancer with cardiac implantable electronic devices (CIEDs). Radiotherapy was evaluated on CIED malfunction. Radiotherapy in patients with cardiac implantable electronic devices is associated with device malfunctions in up to 7% of patients, with the risk increasing to 20% when neutron-producing radiation is used.
